[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0030] Specific implementation method 1: Combination Figure 1-8 As shown, a cotton pulp board purification and filtering device comprises: a frame 1, a lifting device 2 is respectively provided at both sides above the frame 1, two filter plates 3 are installed on the lifting device 2, the two filter plates 3 are arranged up and down, and a detachable retaining wall 301 is provided above the filter plates 3, and a combined track 4 is provided in front of the frame 1; a cleaning member 5, the cleaning member 5 is connected to the combined track 4, and the surfaces of the two filter plates 3 are cleaned under the drive of the combined track 4;

[0031] In the working state, the cotton slurry is poured onto the filter plate 3. After being filtered by the double-layer filter plate 3, the larger impurities in the slurry are effectively filtered to improve the quality of the slurry. After a period of use, some fibers or other impurities will adhere to the filter plate 3. At this time, the filter plate 3 is driven to move downward by the lifting device 2 to release the clamping and fixing of the baffle wall 301, and then the two baffle walls 301 are removed, and the cleaning piece 5 is located on the upper surface of the two filter plates 3 by relying on the combined track 4. Then the height of the filter plate 3 is adjusted to achieve full contact, and then the filter plate 3 is cleaned. Compared with the traditional manual cleaning after dismantling, the cleaning efficiency is effectively improved, the operation is simple, the labor intensity of the staff is reduced, and the maintenance time is shortened.

At the same time, the lower end of the rod 202 passes through the frame 1 and the filter plate 3 in sequence to form a sliding connection, and two stoppers 203 are provided at the bottom end of the rod 202. The hydraulic cylinder 201 drives the rod 202 to move up and down to adjust the height of the filter plate 3. After the retaining wall 301 on the filter plate 3 is removed, the two stoppers 203 are used to support the bottom of the filter plate 3 to prevent the two filter plates 3 from being closed together, resulting in a situation where they cannot be cleaned.

[0033] In a preferred embodiment, the spacing height between the two stop plates 203 is smaller than the height of the retaining wall 301, thereby effectively avoiding interference. When the spacing height is greater than the height of the retaining wall 301, during the clamping and fixing process, the upper filter plate 3 may be fixed under the push of the stop plates 203, while the lower filter plate 3 has not yet reached the clamping position.

[0036] In a preferred embodiment, the cleaning member 5 includes a support frame 501 and a brush roller 502; the support frame 501 is in contact with the upper surface of the second track 402 and is threadedly connected to the driving screw 403; there are two brush rollers 502, which are arranged at a distance from each other on the left side of the support frame 501, and the brush roller 502 is connected to the support frame 501 by a rotating shaft. When the first track 401 drives the support frame 501 to move laterally, the brush roller 502 rotates at the same time to quickly clean the surface of the filter plate 3, and the cotton thread is wrapped around the brush roller 502, while larger impurities can be moved to the edge under the push of the brush roller 502 and can be cleaned again. Specific implementation method 2

[0038] Combination Figure 6-7As shown, a detachable shield 503 is provided on the support frame 501, and the shield 503 and the brush roller 502 are arranged concentrically. During the cleaning process of the brush roller 502, the occurrence of splashing of debris is reduced, thereby improving safety during work.

[0039] In a preferred embodiment, scrapers 504 are symmetrically provided on the shield 503, which can realize secondary cleaning of the filter plate 3 during the displacement process and can reliably push the debris to the edge.

[0040] In a preferred embodiment, the inner wall of the protective cover 503 is provided with a comb plate 505 in contact with the brush roller 502, and the comb plate 505 has evenly arranged gaps. When the brush on the brush roller 502 passes through the gaps, the cotton fibers adhering to the brush can be scraped off and gathered, which is convenient for subsequent cleaning.
